  • Input voltage clamp for a single-supply system
    Patent number: 8031448
    Abstract: A system, apparatus and a method are described that provide a voltage clamp for a single-supply system. In particular, a negative voltage clamp prevents a negative over-voltage in a system having only a positive independent voltage source. For example, certain analog-to-digital converters and other circuits allow input signals below the negative supply, or ground in single-supply systems, either by direct sampling or using input attenuation resistors. The negative clamp allows the circuit to provide accurate negative over-voltage protection and the absence of this claim would result in over-voltage protection in positive voltage directions only.
